No, whether or not selling 40k is enough to satisfy Falcom is a reasonable question. Ys 8 seems to be a bigger game than Celceta and it also seems to have a higher focus on story, presumably in order to appeal more to Falcom's Trails audience. Is selling on par with Celceta enough with that in mind? Or was Falcom hoping for considerable growth?
I love the Ys series and I definitely don't want 8 to be an underperformer, but looking how even Tokyo Xanadu sold double as much in its FW, I do wonder what the future of Ys is. At this point, it feels like it's a series they keep due to tradition and not because of its success (at least looking at its domestic market).
